I bought this 50i back in October and haven't had any issues with it till now...I went to open the drivers side door with the key fob in my pocket as I do everyday and nothing happened...So I used the key fob to unlock the doors and attempted to start the truck without using the key fob and nothing happened...I slid the key fob in and the truck started no problem so I figured maybe the key fob battery was dead and replaced it...I tried opening and starting the truck without using the key fob and got the same result again nothing happened??? I know the battery works because I put it in my other key fob I use for my other BMW with CA...Has this happened to anyone else or is the truck going to need to be recoded by BMW?
